SIT Gas Conversion for Top Convertible Pilot – Part B (series 0190XYZ)
Instructions for converting SIT 190 series pilot burner injector from NG to PROPANE and from PROPANE to
NG only. This information should be considered as supplemental to the Appliance Manufacturer's
Instructions.
WARNING! The installation of this conversion kit must only be undertaken by a qualified and certified gas
appliance installer.
1. Shut-off the gas supply to the appliance.
2. Allow the pilot burner to cool to room temperature.
WARNING: Touching a hot pilot burner can
result in injury.
3. The pilot hood is held in place by spring. First
remove the spring, then remove the hood by pulling
it up from the pilot bracket (fig. 1).
4. Insert a 5/32" or 4 mm Allen wrench into the
hexagonal key-way of the injector (fig. 2), and
rotate it counter-clockwise until it is free of the
injector journal.
5. Verify that the new injector is proper for the
application. The injector size is stamped on the
side of the injector near the top. Propane injectors
have a groove machined around their
circumference near the top, while NG injectors do
not have a groove (fig. 4). Refer to the Appliance
Manufacturer's instruction sheet for the proper
injector size.
6. Insert the Allen wrench into the end of the injector.
Then, insert the injector into injector journal, and
rotate the injector clockwise until a torque of 9 lbf in
(1.0 Nm) is achieved.
7. First replace the pilot hood by aligning the tab on
the base of the hood with the slot in the side of the
pilot journal, and push the hood down, onto the
pilot bracket (fig. 3). The hood must sit squarely on
the bracket for proper operation. Then replace the
spring by pushing it on his seat (fig.3). Check to
insure that the hood is properly seated onto the
pilot bracket and that the spring is properly inserted
onto his seat.
8. Restore the gas supply to the appliance, and ignite
the pilot burner. Verify proper ignition and
operation.
WARNING!
This conversion kit must ONLY be applied as part of a conversion kit supplied by the APPLIANCE
MANUFACTURER for the specific appliance, and type of gas, being converted.
